ELECTRICALLY-HEATED COOKING UTENSIL.

T oaZZ whom it may 001m 1%:

Be it known that we, FRANK norm and FRANK E. Sn'AiLon, citlzens of theUnited States of America, residing at Detroit, in'

sulates the same from downward radiation.

In the drawings: Figure 1 is a vertical central section through theutensil; Fig. 2 is a perspective view of the ring for securing thebottom and attachingthe legs; and

Fig. 3 is a bottom plan view showing the manner of locking the ring.

A is the vessel for containi ug the material to be heated, and B isad-.;wnwardly projecting skirt which forms beneath said vessel :1compartment C for containing the heating unit. This heating unit D ispreferably of the fiat disk type, and is secured to the bott'om-of'thevessel A by suitable means, such as the studs E and clamping 7 nuts F.

G is .an insulator block for the terminal connections, and H are thecontact posts mounted on said block and extending outward through anaperture in the skirt into a guide housing I for receiving the conductorplug.

J is an enlargement at the base of the skirt forming a shoulder Kagainst which is placed chamber C. There is also preferably a secondplate M beneath the plate L, but separefera'bly connected by struck-outlugs h integral with the .plate L.

For detachably securing the plates L and M in position and for alsoattaching the supporting legs to the utensil, we have provided a splitrin O for engagement with the portion J o the skirt. This ring is formedof resilient material and when closed will exactly-fit withintheiportion J, having Specification of Letters .Eatent.

inwardly-bent flanges P which coiii'e in coni.

tact with each other. Adjacent to the lower edge of the ring 0 portionsthereof are struck-outward to form detents Q, which,

are in engagement with a groove R at the lower edge ofthe portionJ.These detents may be engaged with the groove lt by overlapping the endsof the'ring. when it is first inserted withinthe-portion J, and by thenexpanding the ring until the flanges P abut against each-other, all ofthe detents'will be interlocked with the groove.

The ring 0 in addition toforming a securing device for the bottom platesL and M also forms a means of attaching the feet S which support theutensil. These feet are bolted or otherwise secured to the ring asshown, and'project downward therefrom, so'

that when the parts are assembled they form 'a support, holding theskirt'out of contact with the table.

With :the construction as described, the heat which is generated by theunit D is directly conducted into the bottom of the utensil, while theair space beneath the unit forms an effective heat insulation. Downwardradiation of the heat is further revented by the plates L and M,'both ofw fich are preferably formed of material'having .bright faces, andtherefore forming good heat reflectors. If at any time it is desired toobtain access to the unit, all that is necessary is to spring out one ofthe ends of the ring 0, which will permit of detaching the latter andremoving the plates L and-M.

\Vhat we claim as our invention is:

1. An electrically heated utensil, compris- 5 ing 21 depending skirt, aheating unit ."se

cured to the bottom of said vessel withi'h'jthe space inclosed by saidskirt, a false bottom secured within said skirt below said unit, and asplit ring for holding said false bottom in position.

An electrically heated utensil, comprising a vessel having a dependingskirt, a

heating unit secured to the bottom-of said vessel ,within said skirt, aclosure for the space within said skirt, and means for securing saidclosure also constituting the support for said utensil.

3. An electrically heated utensil, comprising a vessel having adepending skirt, a heating unit within'the space inclosed by said skirt,a closure for the bottom of said Shirt,

I a. split ring for securing said closure, and

supporting feet mounted on said split ring and secured thereby.

for said chamber, within said skirt within said skirt, and a. pluralityof feet.

secured to said split ring and connected by the latter to said utensil.

5. An electrically heated utensil, comprising a vessel having adepending skirt with a groove therein, a heating element in thechamberwithin said skirt, a bottom-closure a split ring for fitting withits ends abutting,

and detents on said ring for engaging said groove.

' 6., An electrically heated utensil, comprisingfla vessel having adepending skirt formchamber for the heating unit, a closure {eyelidchamber and a securing device for said fclomire comprising a. resilientsplit ring having, inwardly-flanged ends and outweirdly-Projectingdetents, said ring being insertib 0 within said skirt when the ends areoverlapped, and said detents engaging locking shoulders in said skirtwhen the ends of said ring abut.

'7. An electrically heatedutensil, comprising a vessel having adepending skirt forming a chamber for the heating unit, bottom platessecured to each other at a spaced distance, below the heatin unit andforming a closure for said chan ber, and means for detachably securingsaid bottom plates in position. I

8. An electrically heated utensil, comprising a vessel having adepending skirt forming a chamber beneath the bottom of the vessel, aheating unit within said chamber, a bottom closure for said chamber, anda split ring for securing said bottom closure within said skirt, saidsplit ring having inwardly-bent flanges at its ends contacting with eachother.

In testimony. whereof we affix our signatures in presence of twowitnesses.
